Insulation effect in wiring terminal blocks and fuse blocks
(OP)
Could anyone tell me what is the proper or most used method for stripping and securing wire in screw type terminal block? should bare wire be seen? Is it bad to have some insulation pinched in the connection? This is refering to 22awg to 18awg wire. Thanks

Insulation pinched in the connector is very bad. Any insulation under the screw clamp is unacceptable.
Bare wire can be seen as long as it can NOT short to an adjacent terminal/wire/etc.

If you "tin" the wires, the screw terminal will vibrate loose over time, if the terminal block in a location prone to shock and vibration, because the tinned wires take a set. Make sure you use some form of anti vibration retaining mechanism on the screws.

Ring tongue terminals have the best safety record, but I find it to be a pain in the rear to always remove the screw. Fork tongues are easier to deal with, but have a risk of squeezing out sometimes (same risk as bare standard wire I suppose). My preference is what are called "locking fork tongue" terminals. They have a shape or protrusions that "snap" around the screw shaft to keep the terminal in place as you tighten the screw. Best of all worlds IMHO.
